'EDGE-TRIMMING LAWN-NIOWER.

SPECIFICATION forming part of Letters Patent No. 362,516, dated May 10,1887.

Application tiled January 6, 1886. Serial No. 187,763. (No model.) l

.To all whom it may concern.l

Be it known that I, DANIEL C. KENYON, of Vyoming, in the county ofWashington and State of Rhode Island, have invented certain new anduseful Improvements in Edge-Trimming Lawn-Mowers; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

The object of this invention is to construct a lawn-mower for trimmingthe edges of grassplots along the walks and close around walls,buildings, dto., and at the same time capable of being used in the usualway in narrow places between plants, &c., where there is not sufficientroom for the ordinary lawn-mower to be used. It is vfully illustrated int-he accompanying drawings.

Figure l shows a side elevation of the lawnmower with 'a part removed toshow the gearing inside. Fig. 2 is a top view of the same. Fig. 3 showsa front elevation of the lawnmower.

The machine consists of a driving-whcel,A, on the inside of the rim ofwhich internal gearteeth, n, are made in the usual way in lawnmowers.This driving-wheel A turns on a stud, g, fastened tothe plate B, thatcovers the open side of the driving-wheel A. The plate B is extended outon its lower front edge to form a sleeve, f, to hold the guard-fingerblock h, which is fitted to turn freely on the outside of the sleeve f,and is provided with a set-screw, m, to hold the block h in any desiredposition.

A short shaft, j, is fitted to turn in the sleeve f, and has a crank, r,made on its outerend, and on its inner end a small bevel gear-wheel, o,is secured, the teeth of which engage a larger bevel-gear, o, held on astud, y, made fast to the plate B. On the inner side of the bevel-gear oa pinion-gear, p, is made fast, (see Fig. 2,) the teeth of which engagethe internal gear-teeth, n, on the driving-wheel A. Through thesegear-wheels p o o motion is communicated from the driving-wheel A to thecrank 1', that operates the knife a, which is secured to the bottom ofthe block d, which is held in position so as to swing freely on a stud,c, made fast in the guard-block h.

The back part ofthe knife-block d is carried upward and has a slot madein it to receive the crank-pin t, so that as the crank revolves theblock and knife'a are swung from one side to the other. The back part ofthe guard-block h is also extended upward and has a hub on the backwhich is fitted to turn on the sleeve f. A ledger-plate, s, is sosecured on the top of each finger of the block h as to be capable ofadjustment, and these plates are set so that the knife a will just swingover them and cut the grass that comes between the ledger-plates s andthe blade a.

As the guard-block h turns around the sleeve f on the same center as theshaft j, it follows that the crank r will operate the block d and knifea in the same manner, at whatever angle the block 7L may be set. Thehandle C is made in a forked shape, the two arms being held on the endsof the stud g, that passes through the center of the driving-wheel A,and the upper end has an eye, through which a crossbar is placed. Thebevelgear o may be connected to the pinion-gear p by means of a ratchetand pawl to operate only when going forward, if desired. f

To use the machine the set-screw m is loosened and the guard-block h setat any angle, according to the use intended, and then secured byscrewing up the set-screw. Ifit is intended to cut the grass left by theordinary lawnmower around buildings, walls, trees, or other objects, orfor use in narrow places between objects not accessible to the usuallawnmower, the block h is set at the lowest position, Fig. l, where itwill operateas an ordinary lawnmower. When it is to be used to trim thesides of the walks or flower-beds, the block h can be set at any anglefrom the lowest point up to on-e in which the knife a will be in avertical position, (see dotted lines in Fig. 1,) and at any'point fromthat position up to the top of the circle it will be in proper positionto trim the lower branches from the under sides of plants, shrubbery, e.

Having thus described my improvements, what I claim as my invention, anddesire to secure by Letters Patent, is-
